Step 1: Create a Custom Exchange Class

Create a new file custom_exchange.py in the freqtrade/exchange directory. In this file, define a class custardtart.py.

freqtrade/exchange/custardtart.py

from freqtrade.exchange import Exchange

class Custardtart(Exchange):
    def __init__(self, config, validate=True, exchange_config=None, load_leverage_tiers=False):

    @property
    def name(self):
        return "custardtart"
Copy

Register it with freqtrade/exchange/__init__.py

from freqtrade.exchange.custardtart import Custardtart
Copy

Add it to /freqtrade/exchange/common.py

SUPPORTED_EXCHANGES = [
    "custardtart",
]
Copy
